My boat is almost five years old and has an aluminum prop on it. I
periodically remove the prop and clean it and lube it and have never
noticed any rust. Everyone told me when I bought the boat that since I
fish only in sal****er I'd have to quickly switch to a stainless steel
prop. Well after 5 years I'd say that they are wrong. Has anyone else
experienced longevity with aluminum props in sal****er or am I just
having a run of good luck?

How many hours per year is your prop in salt water?

Aluminum does not rust. The salt water will pit it and that reduces performance
a bit but if you don't hit anything it should last as long as the rest of your
lower end.
The main reason the people around here like stainless is it will suffer the
slings and arrows of outragously shallow water better than aluminum. SS will
shake off sand, mud, shells and oyster bar hits but a rock will still ruin your
day. Fortunately we don't have much rock here.

You better not notice any rust on an aluminum propeller!

It is a major issue for boats that sit in the water all the time. If your
boat is only in the water 8 hours a week then your prop should last about 21
times as long. It is even worse for boats that are in the water all the
time and left hooked up to shore power as they can develop an electrolysis
path between the shore power "ground" and the water.
